Re: I m geting an engine alarm and the code is P1151 .
A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. is there any change in the drivabilty ?

i have a land rover freelander how does an engine how does engine coil goes bad? also I'm having another problems with my rear windows they don't want to go up or down. I changed the sensors but still not working. can you please help me Thanks
you can unhook the fuel line where it connects to the fuel rail and turn the key on and see if you get fuel but it's risky you don't want it to spill over the engine. you may just need a new filter or maybe an intermittent short at the fuel pump. could even just be the power supply plug for the fuel pump
This problem can be caused by; low engine oil, bad oil pump, or bad or disconnected oil pressure switch. Please identify which engine your car has and which model Jetta it is (2.0T, 2.5,GLI, TDI or Value Edition) in order to establish the location of the components.
I would have it checked out and SOON. Those lights come on for a reason. Namely a sensor has triggered identifying a fault. The longer you drive on it the more things can and WILL get damaged. Don't mean to scare you, but they do serve a purpose. Stop by any good parts store (Autozone, Advance, etc...) and have them do a free fault scan and FIX IT.
Removing the battery connection for this procedure will cause diagnostic trouble codes to be stored in the engine control module. Erasing these DTCs and resetting the readiness code will require Volkswagen scan tool VAG1551/1552 or equivalent. The same results will occur when disconnecting engine management components while the key is in the on position. Some driveability problems may be noticed until the system re-adapts to operating conditions. OBD II readiness codes, which may be required for emissions testing, may also be erased. Convenience electronics (alarm systems, interior light control, power locks, mirrors, and windows) may need to be re-set using a VAG 1551/1552 or equivalent sacan tool.
Some 2001-2003 F-150, 2004 F-150 Heritage and 2001-2003 E-150/250
vehicles equipped with a 4.2L engine may exhibit the malfunction
indicator lamp (MIL) on with diagnostic trouble codes (DTCs) P1131
and/or P1151 (system too lean bank 1 or 2). This condition may be due
to leaking isolator bolts/port gaskets in the upper-to-lower intake
manifold mounting area. This condition is sometimes intermittent and
may not be apparent on a warmed-up engine.
Perform a self test. If DTC P1131 and/or P1151 are the only codes
stored in the powertrain control module (PCM) proceed to Step 2. If any
additional DTCs are present, follow normal diagnostic procedures found
in the PC/ED Manual.
Remove the upper intake and replace only the port gaskets (9H486)
and isolator bolt assemblies (9S479). The new isolator bolt assemblies
use a rubber material that is green in color, do not install the old
isolator bolt assemblies with the black rubber material. Do not replace
any other intake parts or gaskets. While the upper intake manifold is removed, check the exhaust gas
recirculation (EGR) orifices that are pressed into each primary port of
the lower intake manifold. If any of the orifices are plugged with
soot, clean and unplug them with a pick and solvent.
